This exception occurs when the Java object attribute is of type String, while the database column is of type CHAR(n), and hibernate.hbm2ddl.auto is validate in persistence.xml.

There are two solutions:
  1. Add columnDefinition to the @Column annotation: 
    @Column(name = “STATE_CODE”, columnDefinition = “char”)

  2. Remove hibernate.hbm2ddl.auto from persistence.xml.
